Unregulated Contaminant Monitoring Rule Program

USEPA uses the Unregulated Contaminant Monitoring Rule (UCMR) Program to collect data on substances that are not already regulated under the Safe Drinking Water Act (SWDA). Every five years, USEPA reviews the list of contaminants. The Water Authority participated in UCMR3 sampling during calendar year 2015. Monitored substances included metals, perfluorinated compounds, chlorate, dioxane, and hormones. Both total chromium and hexavalent chromium were included in the metals sampling.
